Winds of Change

In just eleven years, since 1997, the proportion of the world’s electricity generated from wind has almost quadrupled. There are some impressive absolute numbers behind this global proportion.

In 2008 Australia’s total capacity increasing by over 50%, China doubled its total installed wind power and growth was 50% in the USA.

With this impressive growth comes an equally impressive challenge. Coal still provides over 40% of the world’s power. While wind is growing at 29% a year, versus coal’s 4.5%, in absolute terms coal still dominates over wind. The International Energy Agency wedges illustrate the challenge.
